Add features to basic code

I pulled this basic code from the internet to build a simple EA for scalping during the active market session. However I would like to add 3 core features:

- stop loss placement to be calculated with deviation (user input) in pips and added (in conjunction with lot sizing) @ previous candle low (for buy order) and previous candle high (for sell order)
- add variable lot sizing function to trade by 0.00% of account balance
- add partial close feature with % levels

2 additional features to be added:

- add time filter (start + stop time in hrs:mm)

- add visual display swap rate of current position being held in top right area

scenario of trade operation will be as follows:

 buy trade entry condition met

1. SL of "30 pips" is calculated at low of previous candle plus deviation of 20 pips
2. final SL of (30 + 20) 50 pips is set and run though variable lot sizing formula to allocate lot size in accordance with risk % specified where 4 lots are executed
3. partial close level 1 is set @ 10 pips to close 25% and 1 lot is closed. partial close level 2 is set @ 15 pips to close 25% and another 1 lot is closed



Thank you in advance

I am willing to donate a small fee of $20 for your help if you can provide code over the weekend......

Thank you in advance
